incoming flow meaning in English

来流
入口流
输入流

There are great differences between ground test of a flight vehicle ' s aerodynamics and that of a dual - mode scramjet when ground test facilities are used to do experiments on a dual - mode scramjet engine , the components of incoming flow and its parameters , including total pressure , total temperature ( or total enthalpy ) and velocity must be simulated . at the same time , since the fuel ' s resident time within a combustor is very short , on the order of one millisecond , it is difficult to measure the flow - fields
进行双模态冲压发动机地面试验研究时，必须要求试验设备能模拟实际飞行条件下来流气体的组分、总压、总温(或总焓)以及来流气体的流动速度；同时由于燃料在燃烧室内驻留的时间很短，一般为毫秒量级，从而使流场物理量的测定显得非常困难。
